Went by a local automotive electronics reseller & installer (Safe and Sound in Manasas VA) and tested my 8700c with their live display model of the Motorola IHF1000. Worked perfectly in all functions. Contrary to some other's experience, I was able to answer calls directly with the Motorola control box (Green phone button). All features advertised by Motorola worked fine over the 30 minutes I spent testing.
